Who's Selling Your Number? Inside the Phone Scam Economy

Your Phone Number is a Commodity

In the digital age, your personal information is valuable currency. Every time you sign up for a sweepstakes, register on a website, or accept complex terms of service, your phone number can end up in the hands of data brokers. These entities package and sell vast lists of phone numbers to telemarketers and, unfortunately, to scammers.

The Anatomy of a Scam Call

Scammers use auto-dialers to blast thousands of calls per minute across UK networks like O2 and Vodafone. To increase the chances of you picking up, they often use 'spoofing' to make the call appear as a local number or hide behind a 'Private' caller ID. This anonymity is crucial for their operation, allowing them to deceive victims while evading law enforcement.

• Spoofing: Faking local numbers to build false trust.
• Auto-dialers: Dialling thousands of UK numbers instantly.
• Private IDs: Masking the number to evade Action Fraud.
